444.5mm(17 1/2”)IADC 517 Drilling Tricone Bit Tricone Rock Drilling Head Bit For Oil Well Drilling Rigs Rock Tricone


 

 

The main ways in which the three cone drill bit crushes rocks are impact and crushing. The impact force and static pressure generated by its longitudinal oscillation all lead to the impact and crushing effect of the teeth on the soil, forming volume crushing pits; The auxiliary methods are sliding and shearing, and the radial and tangential movement on the teeth causes a shearing effect underground, fracturing the rock between the teeth; The erosion effect of the jet is achieved by the rapid jet sprayed from the nozzle, which has an impact effect on the rock underground and assists in the fragmentation of the rock.

Under the effect of drilling pressure and drill string rotation, the teeth crushed and also ate into the rock, and at the same time, there was some sliding and shearing of the rock. When it rolls at the bottom of the well, the teeth above it will successively impact and press into the formation, which can crush a part of the rock at the bottom of the well. At the same time, relying on its sliding, the shear effect weakens the remaining rock between the teeth, causing the rock at the bottom of the well to be completely broken and the wellbore to extend
